Specification of Letters Patent.

Patented June 1?, 1919.

Application filed July 8, 1915. Serial No. 38,656.

To all whom it may concern:

Be it known that I, GEORGE Fisonnurr, a citizen of the United States ofAmerica, and a resident of Chicago, in the county of Cook, State ofIllinois, have invented certain new and useful Improvements in FoldingBeds, of which the following is a specification.

This invention relates to that" type of folding beds in which a seriesof bed-sections are pivotally connected together and to the main frameand are adapted to unfold outwardly from the said main frame, an exampleof which structure constitutes the subject matter of my prior LettersPatent No. 1,078,909, dated Nov. 18, 1913.

And the present improvement has for its object to provide a structuralformation and association of parts, adapted to effect a balancingaction. of the parts in their folding and unfolding movements, so thatsaid movements may be effected with a minimum effort on the part of theoperator, all as Will hereinafter more fully appear.

In the accompanying drawings Figure 1, 1s a longitudinal sectionalelevation on line ccw Fig. 4, illustrating the present construction in aclosed or folded condition.

Figs. 1 and 1 are companion detail perspective views of the duplex hingeconnection between the main frame and the seat section of the bed, inthe respective folded and unfolded condition of the parts.

Fig. 2, is alongitudinal sectional elevationillustrating the parts in aseries of partly unfolded conditions.

Fig. 2 is a detail transverse sectional elevation on line m-w', Fig. 1,of the latching of the seat member of the bed.

Fig. 3, is a longitudinal sectional elevation, illustrating the parts ina fully unfolded condition.

Fig. 4, is a sectional plan view of one side of the bed, in an unfoldedcondition.

Similar reference numerals indicate like parts in the several views.Referring to the drawings, 1 designates the main frame of the presentbed-structure of the usual. box form and provided with the usualtransverse back frame 2 and end arms 3, and in the present structuresaid end arms 3, will have spaced relation to the adjacent parallelrails or members 41- of the main frame 1 to provide working spaces forthe dliplex hinge members 5 by which the seat member 6 is pivotallyconnected to theforward end of the'base portion of the main frame 1 in amanner which imposes an outward longitudinal movement. on said seatmember 6, simultaneous with its pivotal movement, to provide ampleclearance of the surface tufting, etc., with which the parts are usuallyfinished. With the seat member in its folded position, the aforesaidhinge members 5 are wholly within the main frame 1, and an objectionableprojection of the same at the front of the. structure is avoided. Tosuch end each duplex hinge member will comprise a detail construction,as follows 7 and 8 designate counterpart hinge bars associated incrossed relation and pivoted together at their midlengths, with one endof one hinge bar pivoted to the main frame 1, and. with one end of thecompanion hinge bar pivoted to the seat member 6.

9 and 10 designate radius links pivotally connecting the opposite endsof the hinge bars 7 and 8 with the main frame 1, and with the seatmember 6, respectively. In the construction shown, the hinge bar 8,which is pivoted in a direct manner to the main frame 1, will beconnected by the radius link 9 to the seat member 6; while the hinge bar7 which is pivoted in a direct particularly in Figs. 1 and 1 and inaddition the radius link 9 will have an angular or curved form as shown,so as to clear the adjacent pivot end of the hinge bar 7, in the foldingand unfolding movement of the parts.

A material part of the present invention involves the pivotal attachmentof the afore said link members 8 and 10 in an approximately horizontalline, to the main frame 1, as by such arrangement the vertical rise ofthe seat member 6 is reduced to a minimum, thus reducing the stressrequired to be exerted in an initial opening of the folding bed members.At the same time the proper forward travel of said seat member 6 isattained in a manner which afi'ords proper clearance between theupholstery finish on gay,

the adjacent parts of the main frame 1 and seat member 6 aforesaid.

11 designates a supporting foot secured to the seat member 6, andadapted to provide a support for the free end of the same, when saidseat member is in the unfolded condition illustrated in Figs. 2 and 3. p

12 designates the usual upholstered back of the folding bed, pivoted atits upper end to the transverse connecting rail 3 of the end arms 3aforesaid,and adapted to be swung up out of the way, in the folding andunfolding operations of the bed parts.

13, 1 1, 15 and 16 designate a series of four bed members or sectionspivotally connected one to the other, and adapted when unfolded toconstitute a flat bed surface for the mattress and the other accessoriesof a bed. And when in a folded condition said bed members constitute arectangular frame which forms within the main frame 1, a containingcavity for the mattress and bed clothing, and to such end the aforesaidbed members or sections will have a detail structural formation asfollows:

The rearmost bed section or member 13 is provided with a fixed angularlydisposed latch bar 17 at its rear end, and when the bed parts are in anunfolded condition. At said rear end the bed member 13 is pivotallyconnected to the upper ends of approximately vertical radius links 18,which are in turn pivoted in the lower portion of the main frame 1. Inthe final opening movements of the bed parts said radius links 18 areadapted to have a forward swing against the stress of springs 19attached to depending portions of said radius links 18, with a normaltendency toreturn said links to a vertical condition. At the front orend opposite to that above described, the bed member or section 13 ispivotally connected to the next adjacent bed member or section 1 1, andadjacent to such. point of connection, is connected to the main frame 1by means of supporting links 20, pivotally connected at one end to saidbed section 13, and at the other end to the lower and free ends of theswing links 21. The upper ends of the said swing links 21,- ar pivotallyconnected to the main frame 1, and the arrangement is such that When thebed parts are in a fully opened condition, the links 20 and2l willassume a vertical position and provide a substantial support to the bedmembers 13 and 14 against a downward sagging in use.

The intermediate bed member or section 14 above referred to is pivotallyconnected at its forward end to the neXt adjacent intermediate bedmember or section 15, and adjacent to such point ofconnection is also.connected to the seat member 6 aforesaid,

by links 22, of an angular form, and which have at their angularportions extensions or knees 23 adapted to restupon ledges 24. in

neceyee the interior of said seat member 6, to support in a substantialmanner the bed members 1% and 15 against a downward sagging in use.

The intermediate bed member or section 15 above referred to, ispivotally connected at its outer end to the outer or forward bed memberor section 16. This bed member or section 15 controls the height of thereceiving or storage cavity for the mattress, etc, when the bed sectionsare folded together, and accordingly will vary in size to suit differentrequirements. V

The outer or forward bed member or section 16 above referred to, isprovided at its outer end with a folding leg or legs 25 pivoted to saidbed section 16, and with a eompanion folding foot board 26 also pivotedto said bed section 15, with the pivots of the parts in spaced relationas shown.

25 designates a tension spring connected at its respectiv ends to theleg 25 and foot board 26 aforesaid, and adapted to move and hold saidparts in their fully opened and fully closed positions after the. usualmanipulations of said parts by the'operator.

27 designates transverse stay rods extending between side rails of thebed members or sections 14 and 15 and adapted to maintain the same inproper spaced relation in actual use. The stay rods 27 are of the usualhasp or flattened C shape, so that their main portions may lay adistance below the sag point of the usual resilient webs carried by therespective bed sections. In the case of the intermediate bed section 15aforesaid, its stay rod 27, provides a convenient hand grip formanipulating the bed parts as set forth in the operation of the parts.

28 designates a. movable latch bar pivoted to the rear face of the seatmember 6. and adapted to movement in a transverse plane, in onedirection under the influence of a spring 29, and in the other directionunder the influence of a pull-cord 30. The said movable latch bar 28 isadapted to have engagement beneath the fixed latch bar 17 of therearmost bed member 13, to latch the series of bed members in theirfolded condition, as illustrated in Figs. 1 and 2 The operation of thepresent folding bed structure is as follows Assuming thepai'ts to be inthe folded condition shown in Fig. 1, the operator first swings the sofaback 12 into an up position out of the way. After this the pull-cord 30is manipulated to release the latch mechanism 17, 28, and the seatsection or member 6 is then swung position shown in Figs. 2 and 3.

The main part of the above described unfolding movement takes placewithout any movement of the other bed parts and accord ingly can beeffected with a minimum effort on the part of the operator. In itsdescent, mainly by gravity, into its fully unfolded outward into theinverted condition, the saidseat section 6, through its link connections22, with the series of bed sections, will draw the said bed. sections,still in their unfolded condition, into theinclined position illustratedin full line in Fig. 2 of the drawings.

The operator by a pulling action on the stay rod 27 of the intermediatebed member 15, moves the series of bed sections, in a still foldedcondition except as to the rearmost bed section 13, into the horizontaland forward position shown in dotted lines in Fig. 2. After which thebed sections 14, 15 and .16, are serially unfolded into the fullyppenedcondition of the parts, illustrated in ig. 3; i
